684166 divided by 45 
We want to divide 684166 by 45.

Step 1:
45 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 45

Moving on to step 2:
68 divided by 45 is 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 45 from 68 and we're left with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 45

Moving on to step 3:
If we divide 234 by 45, we get 5 and a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 225 from 234, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 45

Let's proceed to step 4:
45 can be fit into 91 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 152.0
The remainder is 1 after subtracting 90 from 91.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 45

Advancing to step 5:
When dividing 16 by 45, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 1520.0
If we take 0 away from 16, we end up with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 45

Advancing to step 6:
The number 45 fits into 166 3 times, leaving a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 15203.0
If we subtract 135 from 166, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
When dividing 310 by 45, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 15203.6
Deduct 270 from 310 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 45 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 15203.68
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
45 goes into 400 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 15203.688
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 15203.688 with a remaining 0.004.
